To ALL WHoM IT MAY CONCEEN:

Be it known that I, EUGENE T. BnowNFIELD, of Smithfield, iu the county of Fayette, and State of Penusylva-nia, have invented certain n'ew and useful Improvements in Apparatus for Tempering Cream Preparatory to Ohurning; and I do hereby declare that the following` isn full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification, in which- Figure l represents a side elevation of my invention.

Figure 2 is a. central vertical section of the same.

The object of my apparatus is to raise cream or milk to the proper temperature previous to churning.

The letter A designates a boiler, and B the vessel foncontaining the milk or cream. In the top of vessel B are solderedv the two pipes e anflf, and to the top of boiler B is secured the short pipe c. D represents a horizontal tube, t-o which are soldered at right angles the two tubes g and h. The tube g, it will be observed', is designed to lit over tube c, and tubeh inside of tube e, thus forming a. conduit for the steam from boiler A Vto vessel B.' The pipefis designed to carry oil` the partially-condensed steam from vessel B. E represents thehail attached to the pipe c, and is used to transfer the boiler A olf and on the furnace from which said boiler receives its heat. v

In operating my apparatus, the pipe D with its attachment will be removed, and the water and milk will be poured into their respective vessels. The steam generated by the ebullition of the water, will be conducted into vessel B by means of the connected pipes, as above described. When this process is continued sufficiently long to raise the milk to the proper temperature, it will be then poured into the churn. To ascertain the proper temperature, a thermometer may be adjnstedto vessel B.

Another plan may botndopted for heating the milk or cream, which is to insert a metallic vessel containing.. boiling water into the vessel holding the milk or cream, andsnii'ering it to remain until the. proper temperature is reached. My apparatus, as above described, is the better mode.

It remains only to observe that during the tempering or souring process, the milk or cream should be con stantly agitated, thus allowing it to be more evenlytempered.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

'.lhe within-described process for tempering or soaring cream or milk, when effected by devices constructed and arranged substantially as set forth.

In testimony that I claim` the foregoing as my own, I aiflx my signature in presence of two witnesses. Y

EUGENE T. BROWNFIELD.
